Specification of Letters Patent.

Patented Jan. 29, 3191.

Application filed July 13, 1917. Serial No. 180,248.

vide a loose-leaf binding machine in which the perforating punches are adapted to be swung with the perforated leaves thereon over a series of receiving pins upon which the leaves may then be deposited by depressing a follower carried by the punch head. Also to provide means for clamping the per forated sheets while on the pins to a movable sheet carrier adapted to remove the clamped sheets from the receiving pins into a position for readily sewing or securing them together. Also to provide operating means common to the punches and the movable sheet carrier; also to provide means whereby said operating means may operate the punches without operating the sheet carrier; also to provide means whereby the punches, after they have been brought over the receiving pins and deposited the sheets thereon, may assist in the clamping of the sheets to the sheet carrier; also to provide means for holding the sheet carrier and clamp carried thereby in proper position for sewing or securing the clamped sheets I together; also to provlde an anvil which will retain the punched out material against fallin out and littering up the room in whichthe machine is placed; also to provide an anvil in the form of a tube havingseries of punch openings so that by changin the position of the anvil a new series of openings may be provided. Further objections and novel features will appear hereinafter.

These objects I accomplish. by the construction shown in the accompanying drawings, in which:

Fi ure 1 is a ers )ective oartl in section, of my improved loose leaf binding machine with the parts in position for punclimg. n

Fig. 2 is a plan thereof.

Fig. 3 is a sectional side elevation.

Fig. 4 is a sectional side elevation of a portion of the machine on an enlarged scale with the punches entering the anvil.

Fig. 5 is a longitudinal vertical section through the machine with the punches in line with the receiving pins J.

Fig. 6 is a fragmentary sectional view, showing the punches acting on the sheet clamp.

Fig. 7 is a bottom plan of the sheet and clamp carrier. 7

Fig. 8 is a perspective of the anvil and its closure.

Fig. 9 is a perspective of the sheet clamp.

Fig. 10 is a sectional view, showing the sheet carrier locked in its vertical position to permit sewing or securing the clamped sheets together.

Fig. 11 is a perspective of the casing containing the machine.

The machine casing is in the form of an oblong box and comprises three superposed sect-ions, viz.: the bottom A, open middle section A hinged at a to the upper rear edge of the bottom A, and top section A secured when not in use by four long bolts a passed down through the corners of all three sections and having nuts [4 at their threaded ends to firmly bind the sections together. To the ends of the bottom ii are pivoted the slotted braces a engaging with their slots thethreaded studs on the ends of the open middle section A; the studs a wardly and clamped in its vertically disposed position by the thumb nuts a B designates two or more letter receiving pins projecting downwardly from the inner side of the free edge of the middle sectionli and upon which letters and papers may be impaled temporarily.

C designates a letter or leaf receiving box in open triangular form so that when placed with its apex downwardly on the lower side bar of the middle section A its upper edge or base may be sprung under the opposite or upper side bar of said section A and the box he held between said side bars or may be held by pins. Owing to the downwardly converging sides 0 0 of the letter box 0, the letters or sheets as thrown into the box will be evened and form an even or regular pile ready for action by the mecha nism to be now described. The box C may be held, however, in any desired manner.

Cid

This mechanism may be mounted directly in the bottom A of the case, if desired, but as shown it is carried by a base formed 01 parallel side bars D D bolted as at d d within the bottom A and at that end provided with a. fixed cross axle'or axis E secured reinovably at its apertured ends by the re movable pins 0 extending down through apertures (Z in the inner ends of the side bars D D and the apertures e in the ends of the axle E.

F is a. slotted se mental or curved sheetguide secured at the lower edge of its vertical inner wall to the cross axle E, or a bar mounted thereon while the lower edge of its curved portion having the slots 7' is secured to a'horizontal tubular open ended anvil. housin G; the outer side of the anvil housing G having a longitudinal slot g across its outer face. Below the slot 9 the anvil housing G has a horizontal gage or fiange g bolted to a crosspiece a on the bottom A.

Inwardly from the ends of the anvil housing G extend two side arms mounted between their ends on the cross axle E and extending therebeyond and bolted to the inner faces of the side bars D D. These arms 9 are provided adjacent to the housing G with steps or lugs g for guide rods K, K, to be presently described.

H designates a tubular anvil mounted removably in housing G and provided with parallel series of punch apertures h and having its ends closed; one or both of the end closures h being removable so that the punchings contained within the tubular anvil H may be removed from time to time.

J designates a series of vertically disposed receiving pins secured at their lower ends in any suitable manner to the cross axle D; a clamping bar J and bolts j being shown in the present instance as securing the pins to the main axle E. The upper ends of the pins J lie adjacent to the upper ends of the slots 7 in sheet-guide F.

K K are two swinging guide rods mounted on the axle E and at their free ends carrying the sliding crosshead K provided with a series of punches K which, when w the guide rods K K are swung down into a horizontal position; register with the exposed series of apertures it in the anvil H.

The punches K are roughened or toothed in any suitable manner so as to retain the sheets thereon after being punched.

L is a tollower also mounted on the rods Ii K and, having apertures through which the punches K pass. The follower L has guide pins Z Z, which extend through cross head K and are connected at their outer ends by a handle bar L. Springs Z Z are interposed between the handle bar L and crosshead K for retracting the follower L.

'M, M are two lever arms mounted on the ends of axle E and are connected at their outer ends by ahandle bar M and so con stitute the main operating lover of the machine.

N N are two links pivoted at their outer ends to the ends of the crosshead K and at their inner ends are pivoted to the inner ends of the lever arms M M to one side of the axes thereof.

It follows, therefore, that when the lever M M is swung up into a vertical position with the guide rods K K resting on the stops 9 of the anvil housing G the punches I will register with the anvil apertures It. By now placing the sheets with their lower edge upon the horizontal gage and between the punches K and apertures h, and then swinging the lever M M to the left, the crosshead K will be moved toward the anvil H, and the punches I will punch the sheets. By now raising the lever M the punches will, through the links N N, be withdrawn from the anvil, but the sheet or sheets will remain on the punches. The operator will now grasp the main lever M with the right hand and the handle bar L with the left hand. By lifting the handle bar L the crosshead, punches and sheets carried thereby will be swung up over the curved slotted sheet-guide F, which prevents the sheets from falling and brings their perforations andthe punches vertically over the receiving pins J. During this upward movement of the crosshead K and punches K the operator will keep moving the lever M to the right out of the way, which causes the punches and leaves to clear the pins.

The handle bar L will now be pressed down so as to cause the follower L to force the sheet or sheets off of punches K onto pins J. The crosshead K may now be swung to the left and down upon the stops g and hand lever M swung up to a vertical position.

Having thus described how the sheets are perforated and placed upon the pins J, I will now describe the means for clamping the sheets together and removing them in a clamped condition into position .for sewing or otherwise securing them together.

0 designates a horizontal vertically swinging clamp carrier pivotally connected at its outer or right end to the two side bars D D with its inner end provided with a plate 0 having recesses 0 to straddle the pins J and permit the tongues formed by the recesses to rest on a support along the upper side of the main axle so that as the sheets are strung on the pins J they will. rest upon the carrier 0 and its attached plate 0.

The inner corners of the plate 0 are cut away to form recesses 0 and back of these recesses the sides of the plate 0 are provided with beveled or countersunk apertures 0 to receive the depending legs 7) p of a Lit removable U-shaped clamp P; the outer sides of the legs 19 7? being formed as ratchets to engage the. edges of apertures 0 The crossbar p of the clamp has a handle 19 and a Wide bearing plate 79 projecting toward the pins J when the clamp is in place.

The clamp and sheet carrier 0 is actuated as follows: Two cams M? extend from the hubs of the lever M and when the lever M is swung down to the right into horizontal position these cams M project inwardly and downwardly alongside of the ends of the slotted plate UK This plate 0 is provided with two transverse slides It, which, when moved outwardly, will. project over the cams M so that in raising lever M the cams M will engage the ends of the slides It and so lift the clamp and sheet carrier 0 and with it the pile of sheets to free thepile from the pins d. When the slides R- are retracted stops 1 a at their ends will cross the recesses 0 and so prevent the guide rods K K from swinging too far. That is to say, the stops 1 'r' 1' hold the rods K K with the punches K K in vertical. alinement with the pins J until the said stops are moved outwardly,

away from the recesses 0 When the clamp P is in place over a pile of sheets S and their covers S as shown in Fig. 6, and the slides R It have been moved outwardly to project their ends over cams M and remove their stops 7" r from recesses 0 0 the guide rods K K may be swung into the said recesses, which will cause the crosshead K and punches K K to overlie the flange p of the clamp P. By now holding the handle bar L and lifting the lever M the links N will exert a down pull on the crosshead K and cause the clamp to move down upon the pile of sheets while at the same time the cams M are lifting the free end of the carrier 0 toward the descending crosshead and punches and so a double compression is exerted to clamp the pile of sheets upon carrier 0. After the sheets have been sufficiently compressed the crosshead K and the lever M will be moved out of the way and the carrier f) with the clamped pile of sheets will be swung up into a vertical position, as shown in Fig. 10. I

The formrof clamp to be actuated as above described may be varied as desired without departing from the spirit of my invention. I will now describe the means for operat: ing the slides It It and locking the carrier in its vertical position. The slides R R are provided with longitudinal guide slots 7* r,

through which are passed headed pins or screws 2" 1, which hold the slides to the lower face of plate 0 and the inner ends of the slides are provided with lugs or ears 1 1' between which the head 2 of a rock shaft T works. The rock shaft T extends along the lower side of the swinging carrier O to the hinged. end thereof, and is there provided with a handle t, which projects up through a slot 0 in the carrier. By throwing the handle t rearwardly the head i will be turned flatwise between the lugs or ears r passing the center to keep it in position, and so move the slides R outwardly in opposite directions for the purpose heretofore described. A bow-spring U serves to press the slides It R inwardly.

In order that the carrier 0 may be held in its vertical position as shown in Fig. 10, I provide the end crossbar a of the bottom A with a slot a, into which the handle 6' may be turned and where it will be held by the force of the spring U upon the head t at the opposite end of rock shaft T.

With the carrier 0 thus swung up with the sheets clamped in place the perforations in the pile will be exposed through the recesses 0 in plate O so that the needle and cord or other fastening means may be passed through the perforations. \Vhere such sewing is employed to bind the pile of sheets and their covers the projecting portions of plate 0 between the recesses 0 serve to hold the thread in passing from one line of perforations to the other in the pile. The

thread in so passing from one set of perfora-- tions to the other will be drawn under said projecting portions of plate 0 and so be held against the adjacent sheet or leaf.

It will be seen that I have provided a simple, neat and eiiicient ofiice fixture by means of which it is possible to punch and file the days correspondence of the largest office as the bills and letters come in and at the same time have the same exposed to view.

In using the device the days letters accuniulated and evened in the triangular box may be punched and transferred to the se ries of receiving pins J a back having been first punched and transferred to the pins. At the end of a stated period, say a month, the pins J will have become filled and then a cover is punched and transferred to the pins over the pile of letters or sheets. Then the clamp P will be applied and forced down upon the pile of sheets as just described, after which the carrier 0 and the clamped pile may be swung up into vertical position with the sheet perforations extending horizontally so as to be in the most convenient position for the passage of a binding cord or other fastening means. The pins B, punches K and pins J will be correspondingly spaced.

Various modifications may be made in the machine without departing from the spirit of my invention.
